always wondered how the American Reg's were worked out.....and I take it the American reg 'N' stands for North America? Standard.
John.
Actually John, it's not so much "how it works" as how Piper decided to do it. In the US you can reserve any currently unused registration as long as it meets the format (1-3 numbers, 0-2 letters, no more than 5 characters total, no "O" and no "I" since too easy to confuse with 0 and 1). Back in the 1960s, Piper chose to reserve blocks of registrations as described above for its airplanes. It had a block for all its productions, as did Cessna, Beech, and all the other manufacturers. The Airlines had their own as well.
Also, the "N" doesn't stand for anything in particular, it was just what the US Government had decided on for its government radio stations years prior while reserving "K" and "W" for civilian radio stations positioned West and East of the Mississippi River respectively. But why "K" and "W"? There's no documentation that says definitively, so it appears it was just arbitrary, much as the "N".
Also, remember that "G" is not the only letter that Great Britain got. It also got B and M, now used for China and Isle of Man respectively. Great Britain was actually "K" originally prior to the 1909 International Air Navigation Convention for "United Kingdom", but conflicts with the US Radio Station designation and its use in civil radio elsewhere resulted in "K" being removed from use completely in Air Navigation and Registration.
